CRUISIN'

Okay, so today I booked a cruise in November for me and DH's 20th wedding anniversary. We've never been on one and always wanted to go. (I had to come up with something good because he's taking me to Italy next June for my 40th birthday and one year surgery anniversary). Anyway, here's the problem. I've gone from a size 28 to a 22 in two months. The cruise is three months from now. Anybody got a "best guess" as to what size I might be in three months, assuming I continue to exercise and follow the program? There are some great sales on cute swimsuits, summer clothing, formal attire, etc. right now, but I am completely stumped. I got all excited and caught up in this "great gift" idea and maybe didn't think it through, but what's done is done. So, anybody out there have any wisdom? -Paige
